Battery dies fast and ipod heats up

Hey Everyone, my gf just got her ipod touch 2g 8 gig yesterday and we updated it to 2.2. Since then her ipod gets pretty hot, she mainly plays games on it. Mine doesn't seem to have the issue. And the battery dies fast. Whats up?

tell her to stop playing the games then.....
the ipod probably needs to generate ALOT of the energy in the battery to operate the controls [i.e touching the screen and the ipod responds] and the sound the gamecreate
